Localization Determination for Mixed Reality Systems

4. The method of claim 3, wherein converting the first pose relative to the matching keyframe into the pose relative to the shared map area origin point comprises performing first and second transformations on the pose relative to the matching keyframe, the first transformation is from the shared map area origin point to the matching keyframe, and the second transformation is from the matching keyframe to the keyframe captured by the augmented reality display device.

6. The method of claim 1, further comprising transmitting location-based content in response to at least one of identifying the map area, identifying the matching keyframe, or determining the pose, wherein the location-based content corresponds to data for one or more objects or one or more applications associated with at least one of the map area, the matching keyframe, or the pose.

7. The method of claim 1, further comprising transmitting user data for performing content sharing in response to at least one of identifying the map area, determining the matching keyframe, or determining the pose, wherein the content sharing comprises one-way or two-way exchange of content between devices over a local communications network.

8. The method of claim 1, further comprising transmitting map area data in response to identifying the map area; and updating the plurality of known keyframes.

10. The method of claim 9, wherein the first matching frame is different from the matching keyframe.

11. The method of claim 1, wherein the keyframe captured by the augmented reality display device is received from an imaging device coupled to the augmented reality display device, and the imaging device has a known position relative to a user of the augmented reality display device.

18. The method of claim 17, wherein converting the relative pose into the pose relative to the shared map area origin point comprises performing a first transformation and a second transformation on the relative pose, wherein the first transformation is from the shared map area origin point to the first matching keyframe, and the second transformation is from the first matching keyframe to the first keyframe.
